Some science nerds have found this book disappointing. They do not want to see a physicist delving into the realms of philosophy, worse humanities. Everyone wants to separate the subjects. Very few people like a multi-disciplinary approach to reading or learning. I've always like reading books about science and when science mixes with other fields, draws unexpected connections, it shows the universe as a whole – how atoms make up the cells and thus our bodies, how entropy explains the disintegration of things, people, society, and the cosmos, how evolution can explain behavior, religion, myths, beauty, art and music.

Brian Greene provides a concise history of the cosmos though he also goes into some esoteric topics. A very few physicists would like to speculate about the evolution of the mind and the language and the author does it quite well. He also examines consciousness and free will. People are made of particles and underneath the biology there is physics. The book covers the Big Bang to the present day, and to the end of time. I do not agree with all his conclusions but they are worth reading. I found his writing quite fascinating. Greene considers himself a reductionist and can explain a lot of concepts clearly without leaving out anything relevant.

I learned about a few new topics, touched upon a few things that I already known and came away with a new perspective on how all these things combine to make the cosmos. When science meets philosophy, it makes a great reading for me.
